GAS-BURNER AND CARBURETOR.

SPECIFICATION forming part of Letters Patent No. 333,671, dated January 5, 1886.

Application filed J 111121,1885. Serial 'No.172,230. (No model.)

To all whom it may concern:

Be it known that I, NEWMAN A. RANsoM, of Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvemens in Gas-Burners and Carburetors; andI do hereby declare the following to be a full. clear, and exact description of the same, reference being had to the accompanying drawings, forming a" part el' this specification, and to the iigures and letters of reference marked thereon.

The object of my present invention is to indinarily supplied to dwellings, Ste., the admiXture therewith of a proper propolrtien of hydrocarbon vapor; and to this end my said invention consists in the combination, ar-

supplicd with illuminating-gas.

In carrying out my said invention I apply to the end of the supply-pipe and above the burner a carbureting apparatus having the following characteristics, viz: a reservoir or chamber charged with hydrocarbon and provided with an aperture or opening for the passage of the heated products of combustion, whereby the hydrocarbon-supply is maintained at an elevated temperature; an induction passage or passages connectingythe gassupply pipe with the interior of the said reservoir or chamber; and an eduction passage or passages leading from said reservoir or chamber to the burners, whereby the gas as it cornes from the supply-pipe is conducted through the reservoir or chamber and in contact with the hydrocarbon contained therein and delivered to the burners, and the heated;` products of combustion or a portion thereof being directed and conducted through or in proximity to the chamber or reservoir impart sufficient heat tothe hydrocarbon to gradually vaporize the latter and cause it to mingle with the gas.

The invention further consists in the combination, with an apparatus Ahaving the characteristics above described, of a shade or reileetor applied beneath the chamber or reservoir, and serving not only to relieet the light,

but also to assist in directing the products of combustion into the aperture or passage in the carburetor.

It also consists inpassing the tube or pipe leading from the chamber or reservoir to the burners through the passage for the heated products of combustion, whereby the gas after it leaves the carburetor is maintained at a. high ldegree of temperature audits illuminating power augmented; and it further consists in certain minor combinations and arrangements of parts, all as hereinafter more fully described, and pointed out in the claims.

In the accompanying drawings, Figure 1 represents in longitudinal section an improved apparatus for carrying out my said invention. Fig. 2 is a top plan view of the device shown in Fig. 1. Fig. 3 illustrates a modified form of the apparatus in vertical section.

Similar letters of reference in the several figures indicate the same parts.

The improved form of carburetor herein shown as illustrating the main features of my present invention and a practical mode of applying the same is composed of a metal casing, A, surrounding a central tube, B, to which it is connected at the lower end, forminga chamber or receptacle, C, for the reception of thehydrocarbon. The top of this chamber C is closed by a metal head or casting, D, provided with flanges d, or their equivalents, to receive audhold the upper edges of the casing A and tube B. This head or casting D is provided with a cross -pieee or bridge, d', 'formed with two sets of openings or passages, di and d3, the former,'d2, extending from the central passage or boss, di, (to which the supply-pipe E is attaehed,) tothe interior ofthe chamber C, constituting the induction-passages, and the latter, d3, extending from the interior of chamber C to the central passage or boss, d5, (to which the delivery-pipe E is applied,) constituting the eduetion-passages. Attached to or cast integral with the head D is a downwardly-projecting collar or iiange, d, located between the induction and eduction the gas down toward the hydrocarbon contained within the chamber C, whereby the gas as it passes from the supply-pipe through the chamber C and into the delivery-pipe E will be brought into contact and thoroughly mixed with the hydrocarbon vapor generated in the chamber O. The deiivery-pipe E extends through and projects seme distance below the tube B, its upper end being attached to the boss d5, as by a screw-threaded connection, While its lower end is provided with a hollow cap, e, to which a series of radial burners, e', are secured. Beneath the chamber C, and preferably to an extension of the tube B, is attached a re'llector or shade, F, which, in addition toits usual functions, serves to direct the heated products of combustion aris ing from the burners c into the central passage or tube, B. A filling-orifice, f, is formed in the casing A en the head I), and closed with a suitable stopper, f, to prevent the escape of The apparatus, as described, is adapted for use with various hydrocarbons; but is especially designed to receive what is known as dry white7 or albo carbon, which is introduced into the chamber C in lumps or pieces and caused to generate or give oft' hydrocarbon vapor when heated.

It is found in practice that the carbnretingchamber C if made oi' cast-iron, as is usual, is rather slow in getting heated to the desired degree, and that until so heated the maximum of brilliancy is not obtained, and this is more especially the case when iluid hydrocarbonsuch as kerosene--is employed in the carbu,- retor. In order to overcome this objection, and by facilitating the heating of the hydrocarbon when the gas is lighted, thereby producing a brilliant light in a shorter time, I make provision for heating the gas before it enters the carburetor. Such an apparatus is illustrated in Fig. 4, wherein H represents the gas-heater interposed in the supply-pi pe and located,say, about three inches above the carburetor, and in position to be acted upon by the hot air and products of combustion after passing through the carburetor. This heater H is preferably cast in a single piece Yof brass, or other suitable material,(it may be made of two 'or more sect-ions, it' desired,) with a plate or diaphragm, h, resting upon studs or projections h, and operating to spread the gas, thereby exposing the latter to a larger heated surfacee The carburetor may, if desired, be inclosed within an ornamental casing, I, of metal or other suitable material, and it may project or extend above the top of the chamber C, as shown in Fig. 4, serving not only to conceal the carburetor, but also to deflect the heated air, &c. ,passing through the carburetor against the gas-heater II.

The amount of light given oitfrom the burners and the degree ot' heat to which the .arburetor is subjected can be regulated and controlled by suitable cocks or valves-such, for example, as shown at J, Fig. 1-and, if desired, the delivery-pipe can be made extensible by providing it with asliding joint orsectionas indicated in dotted lines in Fig. 4, w ereby the position of the burners with respect to the carburetor can be varied.

The numerous advantages secured by the arrangement, combination,l and structure shown and described will be apparent to any one skilled in the art.

By the location and arrangement of the carburetor above the burners ample provision is made for heating the carburetor and maintaining it in position where'it cannot interfere with the proper diit'usion and reflection of the light beneath the fixture. Not onlyis the hydrocarbon in the carburetor heated and maintained at the requisite temperature by the heat arising i'roui the burners, but the gas is also heated both before and after it leaves the carburetor, thereby facilitating the operation ot' the carburetor at the start, and by part tially or wholly fixing the mixed gases increasing the illuminating property and preventing condensation in the delivery-pipe.

I am aware that prior to my invention earbureting gas-burners have been constructed, in which the receptacle containing the hydrocarbon is placed over the illuminating-iiame, and is adapted to be heated thereby, as shown, for instance, in Iatent'ho. (32,855, granted to J. Kidd, March l2, 1867, and Iam also aware that devices for heating the gas before it reaches the carburetor have been employed, and therefcre I do not desire to be understood as claiming these features, broadly.
